Creation of mesh and hypothesis function

Creation of mesh and hypothesis function

I am new to SALOME and I am trying learn how to use it and do 3d drawings. I have the SALOME version 5.1.3 and I am doing some tutorials which was for version 2.2.2 which is pretty old version. I have managed to do the first part of tutorial but I am stuck on the mesh part. I actually need to create hypothesis, but i cannot even locate the hypothesis icon on my SALOME, and this icon exists in the earlier version. Can anyone please help me, on mesh creation, algorithms and hypotheses since I cannot find these icons.

Also, if possible can you please advise me where I can find more recent tutorials for 2d and 3d drawings.
